Research Abstract

We have been conducting a search for T Tauri stars toward optically selected dense cores with the Wide Field Grism Spectrograph 2 (WFGS2) on the University of Hawaii 2.2-m telescope. These T Tauri stars would be unbiased samples for future studies of the protoplanetary disk and exoplanets. We have searched more than 50 dense cores and found more than 100T Tauri star candidates.
